Pamphilius sylvaticus - Hedgerow Spinner
This leaf-roller is the commonest species in this genus, widespread as far north as northern Scotland (Musgrove, 2022). The abdomen is black without a band of reddish-yellow on the middle segments. The third antennal segment is clearly shorter than the scape and about the same length as, or less than, segment four. Scutellum yellow. Antennal scape dark marked at the base of the inner side. Head usually with conspicuous yellow spots behind each eye.
Pamphilius sylvaticus larvae on hawthorn, blackthorn etc., and rowans. They create a leaf-roll from within which they feed.
